Since the beginning of their careers in the late '90s, [artist id="509026"]Christina Aguilera[/artist] and [artist id="501686"]Britney Spears[/artist] have been portrayed in the media as pop-star rivals. However, years down the line, Aguilera says she's got her fellow 'Mickey Mouse Club,' alum's back.

According to OK! magazine, Xtina had some kind words for Britney when she was asked during the promotional blitz for her new gig as a judge/mentor on NBC's upcoming TV talent competition, [article id="1659073"]"The Voice,"[/article] if she'd heard Spears' new album, Femme Fatale.

"I've been really hard at work on this show. I haven't had quite the chance to go through the whole thing," Aguilera admitted, but added, "I am a huge supporter of [Britney] in light of the fact that both of our careers started off together and are still going and going strong.

"I just think at this point in the game it's extremely important to be supportive of fellow artists and especially females who get pitted against each other and torn apart."

[article id="1637525"]Aguilera, who also endured comparisons with Lady Gaga[/article] during the release of last year's Bionic album, further commented on the special place that the "Hold It Against Me" singer holds in her heart because of their shared career beginnings.

"As an old friend of mine from the Mickey Mouse Club, I think it's important at this stage in the game to show my support," she continued.

With new projects on both of their plates, Aguilera took to Twitter just last week to send out well-wishes to her fellow pop vixen on her new release, writing, "Hey @BritneySpears Congrats on Femme Fatale release! Can't wait to see what you bring in the next video. xo." Spears responded shortly thereafter, tweeting, "Thanks @TheRealXtina. Can't wait to watch you on your new show. Hope we get to hear that voice on The Voice."
